对转红色荧光蛋白基因唐鱼、野生型唐鱼Ⅰ和野生型唐鱼Ⅱ的耐温和耐氧能力进行比较研究。结果表明,在驯化温度为30℃,升温速率为1℃/h时,3种唐鱼的半致死高温分别为
(38.53±0.08)℃、(38.28±0.29)℃和(38.55±0.09)℃。在驯化温度为25℃,降温速率为2℃/d时,3种唐鱼的半致死低温分别为(1.13±
0.40)℃、(1.26±0.10)℃和(1.21±0.12)℃;恒温25℃时,测定3种唐鱼的窒息点分别为(0.66±0.02)mg/L、(0.74±0.21)mg/L和
(0.51±0.01)mg/L。差异显著性检验表明,3种唐鱼对温度和溶氧的耐受力无显著性差异(P>0.05)。 |

The tolerance to extreme water temperature and lower dissolved oxygen were compared among the red fluorescent protein transgenic Tanichthys albonubes,wild-type fish I and wild-type fish .The results were as follows: when the acclimation temperature was 30℃,and the rate of temperature increase was approximately 1℃/h,the high semi-lethal temperatures of three different stains were(38. 53 ±0. 08) ℃,(38. 28 ±0. 29)and(38. 55± 0. 09) ℃,respectively. When the acclimation temperature was 25℃,and the rate of temperature decrease was 2℃ /d,the low semi-lethal temperatures of three different stains were(1 .13±0. 40) ℃,(1.26 ±0.10 ) ℃ and(1 .21 ±0. 12) ℃,respectively. Under constant temperature 25℃,the asphyxiation points of them were (0. 66 ±0. 02)mg/L,(0. 74±0. 21)mg/L and (0.51±0.01)mg/L, respectively. Significance test of difference indicated that there were no significant differences (P<0.05) in the tolerance to extreme water temperature and dissolved oxygen among three strains of T. albonubes .
